What is the basic separation requirement for IFR flights along parallel runways?

The basic separation requirement for IFR flights operating along parallel runways is typically 1,500 feet vertically or 3 nautical miles laterally. This standard ensures that aircraft maintain a safe distance from one another in both vertical and horizontal dimensions, minimizing the risk of collision or interference during operations. The lateral separation of 3 nautical miles is particularly important when considering wake turbulence impacts, which can be more pronounced when aircraft are operating in close proximity. The vertical separation of 1,500 feet further provides a buffer to accommodate for any potential altitude deviations or unintended descents. This operational protocol is crucial for maintaining safety and efficiency in busy airspaces where IFR traffic is common.
